This has probably been going on for decades, but I guess nobody coined a term for it until now.
It sure makes sense though. There are some products/brands that I avoid like the plague, specifically because they are used/endorsed/associated with certain, how shall we say, well-known individuals. Smart brands would distance themselves from these train wrecks long before there was any kind of link to them.
Ahem, Hilton hotels, I’m looking at you.
